Atonement makes perception unnecessary.

As long as perception lasts prayer has a place. Since perception rests on lack, those who perceive have not totally accepted the Atonement and given themselves over to truth. Perception is based on a separated state, so that anyone who perceives at all needs healing. T-3.V.10: 1-3

The separation causes a sense of lack. This sense of lack leads to perception with judgment rather than an experience of the Atonement which is the undoing, or the healing of the separation, also called a “miracle.” When the Atonement is accepted perception no longer makes any sense.

In Alcoholics Anonymous it is suggested, in step eleven, that we improve our conscious contact with God. This improved conscious contact with God is what the Course calls the “Atonement.” This conscious contact with God is the healing of the separation. When this conscious contact or Atonement occurs, perception is no longer necessary and we no longer take other people’s inventory or our own. There is no longer any inventory to take because we are assumed into the unconditional love of God.

In Unitarian Universalism we covenant together to affirm and promote the inherent worth and dignity of every person. This inherent worth and dignity is a recognition and acknowledgement of the Atonement. Perception is no longer necessary because in the Unconditional Love of God there is nothing to perceive, nothing to discriminate, nothing to judge. Human beings are merely an extension of God’s creation.

Today, it is suggested that we reflect on the Oneness of God, the ocean instead of the drops. When we consider the ocean of God’s unconditional love there is nothing to perceive. We simply experience our completeness, our fulfillment, the Ground of Being.
